RESUMEN

Background/aim: In ulcerative colitis (UC), serum vascular endothelial growth factor (sVEGF) concentrations are elevated and there are conflicting results about serum calprotectin (SCP) and sVEGF as biomarkers. We aimed to evaluate the relationship between sVEGF and SCP levels in UC patients and the associations of these molecules with the phenotypes of UC. Materials and methods: This prospective case-control study included 60 UC patients and 30 healthy controls. The Mayo Clinical Score (MCS) was used to evaluate patients' clinical features and the Mayo Endoscopic Score (MES) was used to evaluate endoscopic features of the cases. The method proposed by Truelove and Richards was applied in calculating the histology activity index (HAI). Human sVEGF (Cat.E0080Hu) and human calprotectin (Cat.E4010Hu) kits were used for the enzyme-linked immunosorbent assay (ELISA) measurements of sVEGF and SCP levels. Results: The median sVEGF and SCP levels were higher in the patient group compared to the healthy control group [2139 ng/L (126-5783) vs. 888 ng/L (715-5270), p = 0.002 and 932 ng/L (99-2648) vs. 80 ng/L (56-920), p < 0.001, respectively]. There was a strong correlation between SCP and sVEGF values (rho = 0.819, p < 0.001). The MCS, MES, and HAI values were positively correlated with sVEGF and SCP concentrations. Conclusion: sVEGF and SCP may be valuable auxiliary biomarkers for UC.

RESUMEN

BACKGROUND: Shortand long-term lung damage after coronavirus disease 2019 (COVID-19) has been emphasized in many studies, but pulmonary-specific health-related quality of life (HRQOL) has been examined only in a limited capacity. OBJECTIVES: In this study, we aimed to assess pulmonary-specific HRQOL and dyspnea among patients hospitalized for COVID-19 by applying the St George's Respiratory Questionnaire (SGRQ) to patient groups 1, 3 and 6 months following discharge (groups T1, T3 and T6). MATERIAL AND METHODS: This cross-sectional study was conducted between April 2020 and December 2020 at a tertiary hospital in Turkey. A total of 345 patients with a definite diagnosis of COVID-19 were included in our research. RESULTS: Total SGRQ score was significantly lower in the T6 group than in the T1 group (p < 0.001). The SGRQ-Symptom score was similar in the T3 and T6 groups, while the T1 group had significantly higher values (p < 0.001). The SGRQ-Activity score was significantly lower in the T6 group than in the T1 and T3 groups (p = 0.001), while the SGRQ-Impact score was significantly higher in the T6 group compared to the other 2 groups (p < 0.001). When the patients were analyzed statistically in terms of dyspnea, the difference between the baseline and 6-month results was found to be statistically significant (p < 0.001). CONCLUSIONS: Although long-term consequences are still not fully known, the SGRQ scores and dyspnea outcomes of our patients show that pulmonary-specific HRQOL and dyspnea remain at a similar level from discharge until the 6th month after discharge. Studies with extended and longitudinal follow-up are required.

RESUMEN

BACKGROUND: Acute pancreatitis is a clinical picture with a wide range of symptoms from mild inflammation to multiorgan failure and death. The aim of this study is to investigate the effects of Adalimumab (ADA) on inflammation and apoptosis in a cerulein-induced acute pancreatitis model in rats. METHODS: Experimental cerulein-induced acute pancreatitis model was created by applying 4 intraperitoneal cerulein injections at 1-h intervals. A total of 40 rats, 8 in each group, were randomly distributed into five groups. In the groups that ADA treatment was given, two different doses of ADA were administered 5 mg/kg and 20 mg/kg as low and high doses, respectively. The rats were sacrificed 12 h after the last intraperitoneal administration of ADA. Blood samples were obtained from each rat for amylase, IL-6, and IL-1ß measurements. Hematoxylin and Eosin (H&E) stains were used to undertake the histopathological analysis of the pancreas. The terminal deoxynucleotidyl transferase-mediated nick-end-labeling (TUNEL) method was used to evaluate apoptosis. RESULTS: : Plasma amylase, IL-6, and IL-1ß levels were significantly elevated in acute pancreatitis groups (p < 0.05). It was determined that both low (5 mg/kg) and high doses (20 mg/kg) of ADA ameliorated the parameters (plasma amylase, IL-6, and IL-1ß) (p < 0.05). Although significant improvements were detected in the Schoenberg scoring system and the apoptotic index from the TUNEL method after highdose ADA treatment, no significant amelioration was observed in the histopathological examinations in the low-dose ADA group. DISCUSSION: : It has been determined that the administration of high-dose ADA effectively alleviated the symptoms of acute pancreatitis and reduced the level of apoptosis. In line with the findings of our study, we have predicted that high-dose (20 mg/kg) ADA can be used as an effective and safe drug in the treatment of patients with acute pancreatitis.

RESUMEN

BACKGROUND: In the current literature, there is a growing evidence that supports the significant role of inflammation in the progression of viral pneumonia, including patients with coronavirus disease 2019 (COVID-19). AIM: The present study aimed to investigate the predictive value of C-reactive protein/albumin ratio (CAR) for in-hospital mortality in patients with COVID-19. MATERIAL AND METHODS: This retrospective study included the data of 275 consecutive COVID-19 patients who were hospitalized in a referral pandemic center. The CAR ratio was obtained by dividing the CRP level with albumin level. The study population was divided into tertiles (T1, T2, and T3) according to their admission CAR values. The endpoint of the study was a composite outcome of in-hospital mortality. RESULTS: During the in-hospital course, 33 (12%) patients died. The patients classified into T3 group had significantly higher CAR compared those classified into T2 and T1 groups. After the adjustment for the confounders, T3 group had 8.2 (95% CI: 4.2-48.1) times higher rates of in-hospital mortality compared to T1 group (the reference group) in a logistic regression model using CAR values. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate the predictive value of CAR for in-hospital mortality in COVID-19 patients.

RESUMEN

Background: To investigate the protective efficacy of pentoxifylline through biochemical parameters and histopathological scores in a caerulein- and alcohol-induced experimental model of chronic pancreatitis in rats.Methods: A model of chronic pancreatitis with caerulein and alcohol was created in female rats of the genus Sprague Dawley. Pentoxifylline was administered in doses of 25 mg/kg (low dose) and 50 mg/kg (high dose) as a protective agent. Each group contained 8 animals. The groups were: group 1 (control group); caerulein + alcohol, group 2 (low-dose pentoxifylline group); caerulein + alcohol + pentoxifylline 25 mg/kg, group 3 (high-dose pentoxifylline group); caerulein + alcohol + pentoxifylline 50 mg/kg, group 4 (placebo); caerulein + alcohol + saline, group 5 (sham group); only saline injection.Rats were sacrificed 12 h after the last injection, and TNF-α, TGF-ß, MDA, and GPx concentrations were measured in blood samples. The histopathologic examination was conducted by a pathologist who was unaware of the groups.Results: The biochemical results of the treatment groups (group 2 and group 3) were statistically significantly lower compared with the control group (group 1) (p < .05). The difference between the low-dose treatment group (group 2) and high-dose treatment group (group 3) was significant in terms of biochemical parameters (p < .05). The difference between group 2 and the control group was not significant in terms of histopathologic scores (p > .05), whereas the difference between the group 3 and the control group was statistically significant (p < .05).Conclusions: As a result, pentoxifylline, which has anti-inflammatory and antioxidant properties, was shown to have protective efficacy in an experimentally generated model of chronic pancreatitis.

RESUMEN

BACKGROUND: Target organ damage is important for global cardiovascular risk assessment. The aim of this study was to explore the association between the blood pressure profile and end-organ damage in a hypertensive non-diabetic cohort. METHODS: A total of 560 consecutive hypertensive nondiabetic patients (mean age: 58.2 ± 13.3 years, 221 men) were included in the study. All patients underwent thorough physical examination including fundoscopic examination. First morning urine samples were obtained from each patient and measurement of the albumin-to-creatinine ratio in first morning urine collection samples was used for diagnosis of microalbuminuria. All patients underwent a 24-h ambulatory blood pressure monitoring and were grouped as dippers and non-dippers according to the presence or absence of >10% decrease in blood pressure during the night, respectively. RESULTS: The non-dipper group consisted of 247 patients with a non-dipper blood pressure profile, 31 patients with reverse dipping and 4 patients with extreme dipping. Non-dipper patients were significantly older. Coronary artery disease, cerebrovascular disease, hypertensive retinopathy and microalbuminuria were significantly more prevalent in the non-dipper patients. Non-dipping hypertension increased the risk of hypertensive retinopathy by 1.89 times (95% confidence interval, CI:1.35-2.65, p < 0.001) and the risk of microalbuminuria by 2.23 times (95% CI:1.49-3.33, p < 0.001). Non-dipping hypertension was still significantly associated with hypertensive retinopathy and microalbuminuria when adjusted by age and sex. CONCLUSION: Non-dipping hypertension was associated with increased risk of hypertensive retinopathy and microalbuminuria. Blood pressure profiles should also be considered in assessing the risk for hypertensive patients.
